Abstract:  
Abstract Laser peen forming, is a purely mechanical forming method achieved through the use of laser energy to form sheet metal. This paper is based on recent experimental investigations on the laser peen forming of thin 1060 pure aluminum sheet carried out in order to understand the effect of process parameters such as laser intensity, number of scanning lines, scanning velocity on the bending deformation. Several thicknesses are selected for experiments. It is found that two bending direction, towards or away from the laser beam, can be obtained with different laser intensity for specimens with different thickness. And if decreasing the scanning velocity or increasing the scanning-line number, the bending angle is increased due to the increase of laser shocks. Keywords: Laser Peen Forming, sheet metal, bending, laser intensity, thickness.
